I I 9 Claims. v This invention jrelates to a slicing and shredding device, and particularly to such a device as may be connected'to a power unit for operating interchangeable implements used inthe same.

'Inmy-United States application for Letters Patent, entitled Electrical utility device, filed April 12, 1932, Serial No. 604,834, there is shown and described a mixing and extracting machine, while in my application'for United States Letters Patent, entitled Power adapter, filed December 6, 1932, Serial No. 645,928, there is shown and described a mechanism associated with the electrical' utility device for providing a two-speed unit adapted for the connection and driving of various implements for household use. The-subject-matter of this invention comprises a device or'implement capable of attachment to the mechanisms above described, and is for the purpose of slicing and shredding vegetables, fruits, etc. g g 'l'his application is an improvement on my application filed December 6, 1932, Serial No. 645,929, and designated Slicing and shredding device; i

The object of the present invention is to provide an improved slicing and shredding device capable of attachment to a power unit for supporting the casing thereof in driving the working implements." 7

A further object of the invention is to provide a' slicing and shredding device which can be manufactured at small expense and which will provide all the advantages of devices constructed of heavier material and at great expense.

According to the invention the slicing and shredding device comprises a drawn metal casing, frustrowonical in shape, and is provided at its inner end with a sleeve for attachment .to a power unit, a working implement of substantially the same shape as the casing, and adapted to rotate in said casing by means of a shait extending through a casing sleeve, and having means on the end thereof for coupling the said shaft to a power take-off unit in the power adapter. w

I he drawings illustrate an embodiment of the invention and the views therein are as follows: Figure 'l isa side elevation of the electrical utility device showing the power adapter incorporated therewith and the subject-matter of this invention operatively connected thereto.

Figure 4 is a top plan view of the slicing and shredding device showing a portion of the power adapter,

Figure 5 is a vertical sectional view of thecasing of the slicing and shredding device, I

Figure 6 is a fragmentary longitudinal sectional view showing the manner in which'the hopper is seamed, 1

Figure 7 is a side elevation of the'cutting implement,

Figure 8 is a side elevation of the shredding In the application of the'power adapter there is described a pair oi 'power take-off members having different speeds and'a portion of which is shown in Figure 2 and identified by the characteristic a. This take-off member is in theform of a shaft 13 having its end slotted at c. Surrounding this take-ofi member is a collar dprovided at its upper end with a winged screw e, th purpose of which will be later explained. j

electrical utility device is also provided with a turntable 29 for supporting a bowl o1 vessel 29 and while that'particular arrangement forms part of the equipment 'for the machine when used as a mixing device, it may be utilized for receiving the sliced and shredded material which is discharged from the slicing and shredding device. g The slicing and shredding device comprises a casing 2i whose interior is frusto conical shape,

and provided with a cut-out portion 22 which communicates with the feed magazine or hopper 23. This casing is made of a drawn metal shell and its inner reduced end-is flanged as at 24 and this flange terminates in an extension 25 which embraces a hub'or sleeve 26.

This hub 26 has an annular shoulder 27 and 'of a tongue 32 of a latch 33 which is operated by a thumb piece 34'. Said latch is pivotally mounted by a shouldered rivet which extends through the flange 24 and plate 28. -The latch is provided with asp ring 36, one end of which is secured to the same near the thumb piece 34, and the other end of which extends into a hole 31 in the annular flange 24 of the casing, so as to urge the tongue PATENT OFFICE 32 of the latch 33 through said slot 3! when pressure is released from the thumb piece 34.

The cutting implements shown in Figures '7 and 8 are, respectively, for the purposes of slicing and shredding and are the same as shown in my former application, Serial No. 645,929, above referred to.

These implements are each provided va shaft 38 having an annular groove 39 and one of these shafts is adapted to fitwitl'rin thehub or sleeve 26 of the casing, and whenthe rib H on the end of the same engages the powertake-nff member by fitting within :the {groove cythe mid groove 39 will be directly in line with the slot 3,|

so that as pressure on the thumb piece is withdrawn, the spring 36 will act to "throw the tongue of the latch into the groove39 and thus secure the implement in the casing. I

The-hopper ;23 'is blankedand shaped from sheet metal and its edges are double seamed, as at 43 in Figure 6. Its lower edge is flanged, as at M, and of such contour as to fit the edges of the cut- .out portion 22 of the casing and the said flange is brazed to said casing.

The casing is provided with a foot or rest 46 which is brazed thereon and which is adapted to rest upon the standard of the utility device, as

' shown in Figure 1.

flange, a sleeve having a shoulder, said shoulder engaging said extension, a plate secured to the inside of the flange and against said shoulder for securing said sleeve. to said casing, an implement having a shaft extending through said .sleeve, an arcuate slot extending through said extension and said sleeve, an annular groove in said shaft, and a latch pivoted to said flange and having its free end movable through the slot to engage the groove in said shaft for removably holding the implement therein. 1 r
